Avaliação técnica e financeira da pavimentação utilizando o piso grama

Abstract

The permeability level comparison between the coating layers adopting massive blocks and grass flooring blocks embodies a key concern during a decision-making process in a paving project. Aiming a higher understanding on the project, it is necessary to consider some facts on the hydrological cycle as the phenomenon of soil water infiltration and superficial drainage. These elements suffer regularly conflict due to a lack of management on the land use; therefore occupation damages are affecting the public order. During the rain water infiltration system execution, an estimation of the permeability coefficient is require, in which correspond to an average speed of groundwater percolation and an infiltration rate. These values represent a volume absorbed in a time and space scale. This project consists on a case of study in which nine samples were presented to characterize some materials from different layers and gears used on the paving. The device used on the field trials was designed to evaluate the infiltration levels using concentric rings. Concluding the project, a budget comparison through both materials were presented.
